Study Overview
Brief Summary
Randomized, balanced, incomplete block design exploratory study of efficacy, with 8 active treatments (4 treatments per subject; 35 or 37 subjects per treatment) compared to a reference treatment (all 72 subjects).
Detailed Description
Incomplete block design cross over study in which the subjects consumed commercial rice porridge (60 grams of extruded rice to which 300 ml of boiling water was added) in the morning in a fasted state. On each visit one of the seven different natural exacts was mixed into this porridge just before consumption. The reference was consumed by all subjects and consisted of plain porridge with no extract added.

- Masking
- Double (Participant, Outcomes Assessor)
Masking Description
Randomization was generated by the bio-statistician CRO. Subjects and key study team personnel were blinded as much as possible with regard to the identification of specific treatments but their distinctive colors, flavors or tastes could not be masked.
To ensure the study team was not apparently aware of the treatments being administered to subjects, persons who were involved in the preparation of test products were not involved in rest of the study.
The sponsors team was blinded.
